SCT and Maksutov telescopes - which of course includes the best-selling models from Meade, Celestron, and other important manufacturers - reverse the visual image left for right. It is extremely difficult to identify lunar features at the eyepiece of one of these instruments using a conventional atlas. The human brain just doesn’t cope well with trying to compare the real thing with a map that is a mirror-image of it. This new SCT version of Hatfield’s famous lunar atlas solves the problem. Photographs and key maps in The Hatfield SCT Lunar Atlas are mirror-images, to show the Moon exactly as it appears through the eyepiece of an SCT or Maksutov telescope. Identification of lunar features is made quick and easy. The Moon’s surface is shown for various sun angles, and there are inset keys that show the effects of optical libration - all mirror-imaged for SCT users. Smaller IAU-standard reference images are included, to make it simple to compare the mirrored SCT photographs and maps with those that appear in other atlases. This edition still uses the superb original photographs taken by Commander Henry Hatfield using his 12-inch reflector. The key maps, on which lunar features can be readily identified, have been reversed and updated, but retain the style and clarity that made the original justly famous.

G. Beutler's Methods of Celestial Mechanics is a coherent textbook for students as well as an excellent reference for practitioners. The first volume gives a thorough treatment of celestial mechanics and presents all the necessary mathematical details that a professional would need. The reader will appreciate the well-written chapters on numerical solution techniques for ordinary differential equations, as well as that on orbit determination. In the second volume applications to the rotation of earth and moon, to artificial earth satellites and to the planetary system are presented. The author addresses all aspects that are of importance in high-tech applications, such as the detailed gravitational fields of all planets and the earth, the oblateness of the earth, the radiation pressure and the atmospheric drag. The concluding part of this monumental treatise explains and details state-of-the-art professional and thoroughly-tested software for celestial mechanics.

For a quantitative understanding of the physics of the universe - from the solar system through the milky way to clusters of galaxies all the way to cosmology - these edited lecture notes are perhaps among the most concise and also among the most critical ones: Astrophysics has not yet stood the redundancy test of laboratory physics, hence should be wary of early interpretations. Special chapters are devoted to magnetic and radiation processes, supernovae, disks, black-hole candidacy, bipolar flows, cosmic rays, gamma-ray bursts, image distortions, and special sources. At the same time, planet earth is viewed as the arena for life, with plants and animals having evolved to homo sapience during cosmic time.

The dark matter problem is one of the most fundamental and profoundly difficult to solve problems in the history of science. Not knowing what makes up most of the known universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial erroneous ‘discovery’ of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe.

This 2000 Edition of Sir Patrick Moore’s classic book has been completely revised in the light of changes in technology. Not only do these changes include commercially available astronomical telescopes and software, but also what we know and understand about the universe. There are many new photographs and illustrations. Writing in the easy-going style that made him famous as a writer and broadcaster, Sir Patrick introduced astronomy and amateur observing together, so that his reader gets an idea of what he is observing at the same time as how to observe. Almost half the book is Appendices. These are hugely comprehensive and provide hints and tips, as well as data (year 2000 onwards) for pretty well every aspect of amateur astronomy. This is probably the only book in which all this information is collected in one place.

Modern astronomical telescopes, along with other advances in technology, have brought the deep sky – star clusters, nebulae and the galaxies – within reach of amateur astronomers. And it isn’t even necessary to image many of these deep-sky objects in order to see them; they are within reach of visual observers using modern techniques and enhancement technology. The first requirement is truly dark skies; if you are observing from a light-polluted environment you need Tony Cooke’s book, Visual Astronomy in the Suburbs. Given a site with clear, dark night skies everything else follows… this book will provide the reader with everything he needs to know about what to observe, and using some of today’s state-of-the-art technique and commercial equipment, how to get superb views of faint and distant astronomical objects.

This is a night by night account of the stars. For every night of the year Sir Patrick Moore gives the reader details of interesting objects that can be seen from earth. It is a book for people with a wide interest in astronomy, those who may not have specialized in a specific area of astronomy and wish to expand their knowledge in all areas. This second edition is updated for astronomical events through until 2010.

This book is about using an 80mm refractor / 90mm Maksutov (such as a Helios 80 or Meade ETX90) as more than a "quick look" instrument, but rather something capable of use as an introduction to scientific observations. Emphasis is on measurement and discovery activities rather than on casual observing. There are two objectives to these activities: to re-enact the process of discovery and to provide amateur observers with the knowledge and skill that will help them make genuine contributions to the field of astronomy.

The physics of scale-invariant and complex systems is a novel interdisciplinary field. Its ideas allow us to look at natural phenomena in a radically new and original way, eventually leading to unifying concepts independent of the detailed structure of the systems. The objective is the study of complex, scale-invariant, and more general stochastic structures that appear both in space and time in a vast variety of natural phenomena, which exhibit new types of collective behaviors, and the fostering of their understanding. This book has been conceived as a methodological monograph in which the main methods of modern statistical physics for cosmological structures and density fields (galaxies, Cosmic Microwave Background Radiation, etc.) are presented in detail. The main purpose is to present clearly, to a workable level, these methods, with a certain mathematical accuracy, providing also some paradigmatic examples of applications. This should result in a new and more general framework for the statistical analysis of the many new data concerning the different cosmic structures which characterize the large scale Universe and for their theoretical interpretation and modeling.

This volume brings together contributions from many of the world's leading authorities on black hole accretion. The papers within represent part of a new movement to make use of the relative advantages of studying stellar mass and supermassive black holes and to bring together the knowledge gained from the two approaches. The topics discussed here run the gamut of the state of the art in black hole observational and theoretical work-variability, spectroscopy, disk-jet connections, and multi-wavelength campaigns on black holes are all covered.
